LUBRICATING DEVICE.

Specification of Letters Patent.

Patented May 12, 1914.

Application filed February 25, 1913. Serial No. 750,624.

To (ZZZ whom it may concern:

Be it known that I, l VILLIAM H. JACK- sox, a citizen of the UnitedStates, residing at Jackson, in the county of Jackson, State ofMichigan, have invented certain new and useful Improvements inLubricating Devices; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to oiling devices fer carpenters plane.

The object of the invention resides in the provision of an oiling devicewhich may be readily associated with a carpenters plane in position toconstitute the forward gripping handle of the plane.

A further object of the invention resides in the provision of an oilingdevice of the character named which will normally prevent the passage ofoil therefrom to the lower face of the plane and which may beconveniently and readily operated to deliver the desired quantity of oilto the lower face of the plane.

lVith the above and other objects in view the. invention consists in thedetails of construction and in the arrangement and combination of partsto be hereinafter more fully described and particularly pointed out inthe appended claim.

In describing the invention in detail reference will be had to theaccompanying drawings wherein like characters of refer ence denotecorresponding parts in the several views, and in which- Figure 1 is aside elevation of a carpenter's plane partly in section and showing theoiling device associated therewith; Fig. 2, is a plan view of a fragmentof what is shown in Fig. 1; Fig. 3, is a section on the line 33 of Fig.2 on an enlarged scale, and Fig. 4, is a section on the line 4-4 of Fig.2 on an enlarged scale.

Referring to the drawings 10 indicates a carpenters plane which includesthe usual bottom plate 11. This plate 11 is provided at its forward endwith a central threaded opening 12.

The oilin device is shown as comprising a head 13 the lower end of whichis reduced and threaded as at 14. The upper end of the head 13 isprovided with a concentric annular flange 15, the outer wall of which isthreaded as at 16. Disposed centrally in the head 13 is a verticalpassage 17 which is ntersected by a transverse recess 18 openlng throughthe side of the head 13. Threaded in the recess 18 is a valve 19 whichis adapted to open and close the passage 17 as will be obvious. Threadedon the flange 15 is a casing 20 which is of a suitable shape toconstitute the forward gripping handle of the plane when the device isapplied as will hereinafter appear. The upper end of the casing 20 isdished as at 21 and provided with an opening 22 for a. purpose that willpresently appear. A ca 23 is threaded on the outer end of the flange 15and is provided with a plurality of diagonal ports 24 and a centralpassage 25 disposed in alinement with the passage 17. Formed integralwith the cap 23 and disposed on the upper side thereof is a casing 26,the upper end of which is provided with an opening 27 disposed inalinement with the passages 25 and 17. Slidable in the passage 25 andopening 27 is a stem 28 which has fixed on the inner end thereof aplunger 29 disposed between the head 13 and the cap 23. Threaded on thestem 28 and disposed in the casing 20 is an adjusting nut 30 andencircling said stem is a spring 31 one end of which bears against theupper end of the casing 26, while the other end thereof bears againstthe nut 30. Threaded on the outer end of the stem 28 and slidable in theopening 22 of the casing 20 is a push button 32. The wall of the casing20 is provided with a threaded opening 33 in which is engaged a stopper34 whereby the casing may be readily supplied with a quantity of oil.

I applying the device to a plane the reduced threaded end 14 of the head1.3 is engaged in the opening 12 and the casing 20 supplied with oil.The valve 19 is then adjusted to allow the proper quantity of oil toflow through the passage 17 As the oil is needed in the operation of theplane it is only necessary to slightly depress the thereof and be fedgradually to the passagel? so that the delivery of oil from said passage17 will be slow and even.

What I claim is z- An oiling device for planes comprising a head havinga reduced threaded lower end adapted for engagement in a threadedopening in a plane bottom, said head being provided With a centrallongitudinal passage and a transverse recess intersecting said passage,a valve threaded in the recess and controlling the passage, a concentricflange on the upper end of the head, a cap threaded on the outer end ofsaid flange and provided With ports, a casing threaded on said flangeand having an opening therein, a stem slidably mounted in said cap, aplunger head fixed on the inner end of said stem and disposed betweenthe head and cap, spring means constantly tending to hold the stem andplunger head in a given position, and a push button threaded on theouter end of the stem and slidable in the opening in the casing wherebythe stem and plunger head may be moved against the tension of saidspring means.

In testimony whereof, I affix my signature, in the presence of twoWitnesses.
